I'm reading (and setup a test system) with the "The Perfect Xen Setup For Debian And Ubuntu" howto. I have a AMD Athlon 1GHZ system for this with 384MB Ram. I needed to enter acpi=force into menu.lst of the host system or else the system wouldn't poweroff properly. Now i installed Xen from source the way Falco explained and have again this poweroff problem, the system wont poweroff totally. I tried acpi=force with Xen but no succes. I can't find any error messages in /var/log the system just doesnt poweroff properly. Debian closes and the hd's stop spinning then the screen says OS stopped or something nothing else. Does anybody know how and if this can be solved with Xen?
